Features
* Maintains mechanical stability at high temperatures between 1100°C - 1200°C, preventing deformation and structural degradation
* Forms a protective chromium oxide layer, preventing oxidation and surface degradation, making it ideal for extreme environments
* Provides high electrical resistance, making it suitable for electrical heating elements and resistance wires
* Ideal for applications where magnetic interference must be minimized, ensuring reliable performance in electronics and
aerospace applications
* Remains ductile and easy to process, even after prolonged high-temperature exposure
* Withstands frequent temperature fluctuations, making it ideal for industrial heating systems and automotive exhaust
applications
* Due to its high durability and minimal permanent elongation, NiCr alloy components retain their structural integrity over
extended use providing longer service life
 
Applications
 * Industrial & domestic heating systems: Used as heating elements in industrial and residential electric furnaces, including electric resistance wires and heating coils
* Aerospace components: Applied in aircraft engine parts and aerospace structural components requiring high-temperature durability
* Chemical & petrochemical processing: Resistant to corrosive environments, making it ideal for reactor vessels, pipelines, and processing equipment

Quality Control

Production process control
Key production stages, such as size measurement and strength testing, are monitored online to ensure product compliance at each stage. We implement real-time monitoring during processes like heat treatment and welding to ensure that process parameters align with design specifications.
 
Finished product quality test
100% inspection of finished products, including dimensions, strength, and resistivity, ensures that the product pass rate is above 99%.
 
* Chemical composition analysis: We have two spectrometers for confirming product compositions through spectral analysis.
* Structural analysis: Equipped with an electron microscope, we can analyze the microscopic structure of materials.
* Mechanical performance testing: Tests include tensile, impact, and elasticity assessments.
* Non-destructive testing: We use an X-ray inspection machine for scanning, radiographic testing, and methods like magnetic particle or penetration testing to ensure the products are free from cracks, porosity, or other defects.
* Appearance inspection: We check the surface of the products for smoothness, and ensure there are no scratches, rust, or other surface defects.
